Abstract

We present solutions to reduce noise in depolarized gyros using low cost laser sources at 1.3 micrometers . Noise reduction is obtained by operating the source in the coherence collapsed regimen, by having the proper depolarizer design and by setting the proper phase modulation depth for optimum signal-to-noise ratio.
